Problems solved by technology

At present, the anti-fog methods mainly include electric heating and the use of anti-fog coatings. The former works well but is expensive and wastes resources. The anti-fog coating is only sprayed on the glass surface, but it cannot be cured, so the anti-fog durability is poor.

Abstract

The invention relates to an antifogging agent composition and a transparent antifogging window membrane formed from the composition. The antifogging agent composition consists of 9-14wt% of hydrophilic resin, 55-76wt% of propylene glycol methyl ether, 3-10wt% of dimethyl methylamine, 1-5wt% of triethylenediamine, 1-5wt% of a levelling agent, 5-26wt% of isopropanol, and 5-24wt% of ethanol. The antifogging window membrane is composed of an antifogging agent coating (1), a transparent polyester membrane or transparent polyethylene membrane base material (2), an acrylic adhesive layer (3) and a release membrane (4), and all layers are integrated. The antifogging agent coating (1) is formed by the antifogging agent composition, while the acrylic adhesive layer (3) is formed by a mixture of an acrylic adhesive, a curing agent, toluene and butanone. The transparent antifogging window membrane has effective antifogging function and high light transmittance, as well as a protection effect.

Description

technical field [0001] The invention relates to an antifogging agent composition and a transparent antifogging window film formed by the composition, which is especially suitable for pasting on the glass surface of a building or the glass surface of a bathroom mirror. Background technique [0002] The fogging on the glass surface of glass doors, windows and various mirrors brings great inconvenience to production and life. Therefore, in recent years, anti-fog and anti-fog processing technology have been widely valued at home and abroad. At present, the anti-fog methods mainly include electric heating and the use of anti-fog coatings. The former works well but is expensive and wastes resources. The anti-fog coating is only sprayed on the glass surface, but it cannot be cured, so the anti-fog durability is poor. Therefore, according to the characteristics of the antifogging agent, it is urgent to develop an antifogging agent and apply the antifogging agent to the window film s...
